ASF Machine Balanced Crank, Nitrided Treated (EJ257)

We have had a number of requests for a precision balanced crank, and we are proud to announce that we now have one. We are working with ASF machine, and having them balance the stock heat treated cranks for us, and they are now available.


The crank's are usually balanced to within 0.3 - 0.5 grams.

They are on our shelf ready to ship, and at most would be about a week out. But we are working with ASF to make sure that these are readily available.

Flatirons Tuning part # is 12200AA430-BAL
